That is because tan always repeats after pi intervals. Lets say for example, n = 2.
tan2x graph will become positive for -ve values of x. But yet it will repeat only after pi intervals. It also remains same for cotnx. All other graphs change with change in powers. Example sin2x . its interval becomes pi.
 
I hope this solves your problem.
